***NEED HELP WITH THIS**** write a code that replicates the list's insert() method. Recall that insert(index, item) method inserts the item at specified index in the list. Write a code that: Asks the user to input 5 items in a list and display the list. Ask the user to input the index where they would like to insert a new item. Ask the user to input the item that they would like to insert into the list. Inserts the new item into the list and displays the modified list. If the index is greater than the length of the list, simply insert the new item at the end of list. Also i dont need to use the list's insert() method to do this program. I dont need to write a function, just the code to replicate the functionality of insert() method.
Do not use Swing for the console output--the console output must be displayed in the console. Write the following code in Java. Using classes of the Java Collections Framework, write a program that allows the user to specify a text file, open the file, and print a two-column table consisting of all the words in the file together with the number of times that each word appears. Words are space-delimited and case-sensitive. The table should appear in the console (do NOT use Swing/JTable) and list the words in alphabetical order. Implement try/catch blocks for cases where the file cannot be opened.

Computer Science Using Java, write a simple Insertion Sort program that can read in integers from a text file (line by line) and sort them into another text file. Use inFile and outFile for the input and output files, respectively. Also make sure that the algorithm keeps track of the comparisons and exchanges performed by the sort so that they may be printed out in the console after the sort is completed

Here is the iterative implementation of binary search: For each call to binary_search below, indicate how many times the code inside the while loop will execute. animals = ["aardvark", "cat", "dog", "elephant", "panda"] 1. binary_search("elephant", animals) 2. binary_search("dog", animals) 3. binary_search("anteater", animals)
Python’s for loop allows the programmer to add or remove items in the collection over which the loop is iterating. Some designers worry that changing the structure of a collection during iteration might cause program crashes. The remedy is to make the for loop read-only, by disallowing mutations to the collection during iteration. You can detect such mutations by keeping a count of them and determining if this count goes up at any point within the collection’s __iter__ method. When this happens, you can raise an exception to prevent the computation from going forward. In the arraybag.py file complete the following in the ArrayBag class: In the __init__ method, include a new instance variable named modCount, which is set to 0. In the __iter__ method include a temporary variable named modCount, which is set initially to the value of the instance variable self.modCount. Immediately after an item is yielded within the __iter__ method, you raise an exception if the values of the two mod…
Description: Given a string, find the first non-repeating character in it and return its index. If it doesn't exist, return -1. Example 1 input: "leetcode" output: 0 Example 2 input: "loveleetcode" output: 2 The solution we are targeting here is a linear time solution since we have to go over the entire string to know which one is unique in it. A straightforward method we can easily think of is having a Dictionary record letter frequency. Subsequently, iterate over the input again and return the index that has a letter frequency of 1.
